I have similar M60 performance in my M850i now and I don't really want that in the iX. The acceleration is loads of fun especially with the exhaust note on the M850i which has a much better sound than my prior M550i. In my case I want respectable acceleration but I don't want to piss off my passengers so 0-60 in the mid 4's is the sweet spot. Now, if the M60 had a tri-motor setup with torque vectoring... in that case, the passengers can bring their own barf bags.
